Design and Analysis of Metal Expansion bellows under Axial and Transverse loadsusing CATIA V5 R21 software

Abstract

Bellow is a versatile seal/expansion joint, whose convoluted element is designed to flex even as thermal moves get up in the piping machine. The form of convolutions relies upon the amount of movement the bellows should accommodate or the stress that want to be used to perform this deflection. The convoluted elements have to be strong circumferentially to face up to the contraction and thermal growth of the device. This strength with flexibility is a totally specific design problem that isn’t often positioned in other additives in commercial machine. Bellows are regularly used in the pressure vessels or piping device, aerospace, and so forth. It has the characteristic to soak up ordinary or irregular enlargement and contraction inside the device. Because of the reality bellows require excessive strength in addition to properly flexibility, we determine upon SS 316 L alloy to layout and manufacture a bellow. The design, manufacturing and evaluation of bellows are extra complex than different contemporary tubes. A magazine associated with layout and production of bellows may be noted. On this study, we bear in mind to format, modelling and detailing of bellows under axial and transverse loading the usage of Expansion Joint Manufacturer’s Association(EJMA) code using CATIA V5 R21 software. With the aid of the use of this EJMA code one can anticipate the circumferential membrane strain, meridional membrane pressure, motion in keeping with convolution and fatigue life cycle of the bellows.
